As representatives of U.S. science, engineering, and higher education organizations, we write to you to express our deep concern regarding amendments that were passed in the Digital Accountability and Transparency Act (DATA Act, H.R. 2146) in the House and the 21st Century Postal Service Act (S. 1789) in the Senate, which would place severe restrictions on government employees' abilities to attend meetings and conferences. We represent hundreds of thousands of scientists, engineers, and mathematicians--many of whom work for the federal government--across a broad spectrum of disciplines.

Our organizations are predominantly non-profit, 501(c)(3) professional societies with a mandate to advance the progress of scientific and technological research and education. Our organizations realize that goal through the publication of peer-review journals, and by convening large scientific conferences, workshops, lectures, and seminars. The free exchange of scientific ideas and information is crucial to advancing science and innovation, and conferences are a standard mechanism for the transfer of information among scientists and engineers.

We recognize that Congress has a responsibility to prevent wasteful government spending. We are concerned, however, that the language in the amendments would inadvertently impede the free flow of scientific information and the professional development of scientists and engineers. This would potentially work against critical national goals related to national security, public health, science education, innovation, and competitiveness.

Recently, Washington D.C. hosted the 2012 USA Science and Engineering Festival, which engaged 150,000 attendees. Many non-profit scientific and engineering societies participated in the Festival, and almost 40 federal government agencies and offices provided hands-on science exhibits and/or public access to government scientists. It is unclear whether government scientists' participation in this education-oriented activity would then preclude their engagement in any other scientific conference in the same year, under the current amendment language.

The undersigned organizations urge you to protect the integrity of the scientific enterprise and encourage you to allow greater flexibility for government employees to attend scientific and technical conferences organized or supported by professional societies and non-governmental organizations.
